The key elements to measure higher efficiency of perovskite LED devices

Who is the winner in the high efficiency contest of LED devices? Light-emitting diodes (LEDs) are the main alternative to traditional light sources, and perovskite light-emitting devices plays the key role in the light-emitting field. Although it is not so easy to get into the light-emitting device field; however, LEDs based on metal halide perovskite materials have extraordinary characteristics: narrow emission line widths at high photo-luminescence quantum yield (PLQY), high color purity...

Solvent-controlled growth of inorganic perovskite films in dry environment for efficient and stable solar cells

Is the inorganic perovskite solar cell a trend in the future? In the highly competitive solar industry, perovskite solar cells have leapt toward commercialization, and challenged the silicon solar cells holding the largest market share at present. Perovskite solar cells have high optical absorption, low cost compared with silicon solar cells, and can be dissolved in solvent and then spray coated directly onto substrate. If its instability and deterioration on exposure to heat problems can ...

Dual-layer tandem technique develops highly efficient perovskite–CIGS tandem solar cell

Waited for three years, the perovskite–CIGS tandem solar cell developed by UCLA Engineering researchers reaches 22.43 % power conversion efficiency. This research was led by Yang Yang, UCLA’s Carol and Lawrence E. Tannas Jr. Professor of Materials Science, also, it was conducted by Qifeng Han, a visiting research associate in Yang’s laboratory, and Yao-Tsung Hsieh and Lei Meng, who both recently earned their doctorates at UCLA. The study’s other authors are members of Yang’s research group...

Characterization of tandem perovskite / organic solar cells

Characterization of tandem perovskite /organic solar cells Do you know there are almost 96% publications reporting tandem OPV characterizations characterized their devices insufficiently or even incorrectly!? The original article is as follows: To the Editor — The tandem solar cell approach is a promising concept for organic photovoltaics (OPVs). However, efficiency determination or, in general, electrical characterization of multi-junction solar cells is challenging. We performed a lit...

Using Solar Simulator light-dependent-techniques to analyze bi-molecule recombination in OPV.

Using Solar Simulator light-dependent-techniques to analyze bi-molecule recombination in OPV. Recently, L. Zhong et al. demonstrate highly efficient ternary norfullerene OPV with two polymer donors and an organic acceptor. The results indicate that adding proper amount (20%) PTB7-Th polymer in the polymer donor could effectively improve in the ternary OPVs. Figure To illustrate the increasing of is due to the suppression of bimolecular recombination by PTB7-Th, they ...
